Total Stripping of the Great Saphenous Vein in Varicose Vein Patients with Thrombophlebitis

Introduction. Patients with varicose disease of the lower extremities may suffer from subcutaneous vein thrombophlebitis with an incidence of more than 50%. However, saphenous vein thrombophlebitis occurs against the background of varicose veins in 80% of patients. Aim. To improve the efficacy of phlebectomy in patients with varicose veins complicated by saphenous vein thrombophlebitis. A modified method of total stripping of the great saphenous vein was developed and introduced into clinical practice in City Clinical Hospital No. 21 (Ufa, Russia). The modified surgical technique is aimed at reducing the severity of postoperative hematomas, increasing the cosmetic effect and reducing the incidence of damage to the cutaneous nerve located near the large saphenous vein. The surgery technique was patented (Patent No. RU2812293C1). Materials and methods. From 2022 to 2023, total stripping of the great saphenous vein was performed in 26 patients with varicose veins of the lower extremities and thrombophlebitis of the great saphenous vein in Cardiac Surgery Department of City Clinical Hospital No. 21. The examined patients were divided into a control group (18 patients) and a comparison group (8 patients). The quality of life of all patients was assessed before and after surgical intervention using the Visual Analog Scale (VAS). Results and discussion. All patients underwent total stripping of the great saphenous vein. Prior to surgery, no statistically significant difference was reported in the assessment of quality of life between the groups. The group of the modified stripping technique demonstrated positive clinical and aesthetic results after surgery. Performing total stripping of the great saphenous vein using the modified technique statistically significantly improved the quality of life in the postoperative period. Control points of examinations were on days 1, 7, 30, 90 after surgery. Conclusion. The comparative analysis of the treatment results proved the efficacy of the modified technique of total stripping in varicose vein patients with thrombophlebitis, including a higher level of quality of life, better clinical and aesthetic result of surgical treatment.

Innovative surgical treatment approaches for endothelial dysfunction : Descemet stripping only (DSO) and endothelial cell injection

Currently, due to arising number of patients Germany and many other countries experience alarge deficit of donor eyes for posterior lamellar keratoplasty procedures in the treatment of corneal endothelial diseases. To address this unmet need there is an ongoing investigation of treatment modalities which do not rely on donor tissue or enable clinicians to treat more patient eyes per donor eye. The authors introduce apromising approach for both treatment principles. First, the technique of Descemet stripping only (DSO) is detailed, in which acentral part of the Descemet's membrane including the endothelium is surgically removed without replacement with donor tissue. This then allows endothelial cells from the periphery of the cornea to migrate into the central area and can reduce corneal opacification and swelling. As arepresentative technique of the second group, the authors introduce endothelial cell injection, in which human corneal endothelial cells are cultivated in vitro and then, after removal of the diseased endothelium, injected into the anterior chamber of the recipient's eye to form anew and healthy endothelium. This is supported by injection of Rho kinase inhibitors and aface-down positioning of the patient after surgery. It is postulated that endothelial cell injection could possibly enable clinicians to treat up to 300 patient eyes with the tissue generated from 1 donor eye. Whether and how these novel approaches will become established in Europe remains to be seen.

Dog Blood Type DEA 1 in Two Municipalities of Luanda Province of Angola (Sub-Saharan Africa).

In dogs, the risk of an acute hemolytic transfusion reaction at the first transfusion is negligible; however, mismatched transfusions may produce alloimmunization. To avoid fatal acute hemolytic reactions in subsequent blood transfusions, it is important to recognize blood groups and to blood type both the donor and the recipient. Prevalence of dog blood groups varies geographically and between breeds. Our aim was to determine DEA 1 prevalence in a canine population in Luanda (Angola) and to assess alloimmunization risk after a mismatched blood transfusion. Blood samples were typed using an immunochromatographic strip technique. Of the 112 dogs tested (59 males; 53 females), 52.68% were DEA 1 positive and 47.32% DEA 1 negative. Females tended to be DEA 1 positive, and males DEA 1 negative (p = 0.0085). In a first-time mismatched blood transfusion, the calculated probability of a dog becoming sensitized was 24.9% and the probability of an acute hemolytic reaction following a second incompatible blood transfusion was 6.21%. DEA 1 prevalence obtained was similar to that reported worldwide, but differs from other African countries. The risk of alloimmunization and acute hemolytic transfusion reactions in mismatched blood transfusions is higher than that in other African regions. Blood typing is recommended prior to transfusion.

Experimental study on the in-plane behavior of mud brick walls strengthened with bamboo strip mesh and dried jute thread

Despite advancements in modern structural engineering, adobe and mud brick constructions persisted as important housing options for a significant percentage of the world's population. However, because of their low strength and brittle nature, they are susceptible to natural disasters, especially earthquakes, which is a concern for many mud-brick buildings found in seismically active areas. To address this issue, this research investigated the in-plane behavior of 4 ft x 4 ft mud-brick walls strengthened with locally available materials i.e. Bamboo Strips and Dried Jute Thread in mesh format with various spacing. The specimens were subjected to compressive and diagonal shear loading separately. The data collected was analyzed to determine the important mechanical properties such as compressive strength, modulus of elasticity, shear strength, modulus of rigidity, and energy absorption. Notably, the bamboo strips technique improved these properties by 30 %, 19 %, 96 %, 82 %, and 195 %, respectively. The dried jute thread wrapping technique, on the other hand, demonstrated even greater improvements with increases of 40 %, 69 %, 102 %, 110 %, and 314 % for the same properties. Based on the experimental results, the proposed technique can be applied to mud-brick wall in seismically active areas.

Combined removal of ovarian teratoma and oocyte retrieval by laparoscopic surgery under regional anesthesia

To describe the simultaneous laparoscopic approach for teratoma removal and oocyte retrieval performed under regional anesthesia in a woman, desiring to preserve fertility. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites, and other applicable sites. Video case report demonstrating the clinical management and laparoscopicteratoma removal combined with oocyte retrievalaccomplished underregional anesthesia. University tertiary care hospital. We present a case of a 31-year-old woman who referred to our Fertility Center with a previous history of right salpingo-oophorectomy for mucinous ovarian cystadenoma and the presence of a large ovarian teratoma of ten centimeters of the contralateral ovary. The ovarian stimulation started in the early follicular phase. Not being able to visualize follicular growth during the ovarian stimulation, it was decided to adopt fixed protocol with antagonist on the 5th day and to proceed, on 15th day, with a laparoscopic pick-up and simultaneous removal of the cyst. Laparoscopic surgery was performed: the left ovary appeared larger in size for the presence of the suspicious mature dermoid cyst and multiple follicles, previously not identified at ultrasound imaging. The follicles contained oocytes that were aspirated with an aspiration needle of 17 G connected to a craft suction pump. Then, practicing the stripping technique, an enucleation of the ovarian cyst was performed. Surprisingly, the removal of the cyst revealed other follicles that were readily aspirated. The patient remained awake during the entire procedure and a low pressure of 10 mmHg was maintained at 15° of Trendelenburg position. A total of seven follicles were aspirated, seven oocytes were retrieved, and six mature oocytes were cryopreserved. The cyst was totally removed and no intracavitary spillage was caused. Simultaneous laparoscopic approach for teratoma removal and oocyte cryopreservation should be considered an effective fertility preservation strategy in patients in whom the presence of an ovarian neoformation does not allow visualization of growing follicles by ultrasound. Laparoscopic oocyte retrieval under regional anesthesia is a safe and well-tolerated technique and should be considered for patients where the transvaginal approach could not be performed.

Characterising Skin Electrical Impedance Using Tape Stripping Methods: A Bioelectrical Study of a Porcine Model.

Background Recent advancements in ultra-low power electronics and wireless devices have facilitated the widespread adoption of wearable technology for fitness and health monitoring, paving the way for personalized medicine. Microneedle-based devices, comprising small epidermal patches that penetrate the skin's stratum corneum to potentially access biomarkers in the extracellular fluid of the viable epidermis, represent a promising innovation in this field. Objectives This project aimed to develop and validate a novel method to evaluate microneedle engagement in the skin in real-time. To our knowledge, there are no studies published to date that have characterized the electrical impedance of stratum corneum and epidermis using the tape stripping method to selectively remove cell layers. Additionally, no studies have been published comparing the electrical impedance of fresh to frozen-thawed porcine skin. The objective of this study was to develop and validate a novel method to evaluate microneedle engagement in skin, in real-time, that does not require processing of the tissue. Methods A tape stripping technique was employed to selectively remove the stratum corneum from fresh and frozen-thawed porcine skin samples which were then electrically characterized using an excitation frequency of 5 kHz with a peak Voltage of 1 V. Results This study demonstrated a mean impedance reduction of 97.08 ± 1.3 % for fresh porcine skin, and 98.04 ± 0.3 % for frozen-thawed porcine skin when transitioning from the surface stratum corneum to the viable epidermis. The correlation between the reduction of impedance and the number of tape strips across all 18 test sites was significant (r = 0.98, p < 0.00001). However, comparing the skin impedance of the fresh and frozen-thawed specimens showed poor equivalence, with the frozen-thawed sites approximately 5.5 times the impedance of the fresh sites before any tape stripping, and 4.19 times greater after 30 tape strips. Conclusions These findings suggest that monitoring for an interelectrode impedance decrease of greater than 95% between two projections of a microneedle device could provide a rapid and effective evaluation of skin engagement, crucial for advancing the development and clinical application of microneedle-based technologies in personalized medicine. The study also underscores the impact of the freeze-thaw process on the mechanical and electrical properties of skin, which is crucial for standardizing testing protocols.

Radial solutions for Neumann problems involving prescribed mean curvature operator in a ball and in an annular domain

Using topological transversality method together with barrier strip technique and cut-off technique, we obtain new existence and uniqueness results of radial solutions to the Neumann problems involving prescribed mean curvature operator div∇v1+|∇v|2=f|x|,v,dvdrinΩ,∂v∂n=0on∂Ω,where Ω={x∈RN:R1<|x|<R2}(0≤R1<R2,N≥2), f:[R1,R2]×R2→R is continuous. Meanwhile, we demonstrate the importance of our results through an illustrative example.

Edema and Trismus Assessment After Applying Kinesiotape With the Web Strip Technique Compared With Cryotherapy: A Randomized Clinical Trial.

Extraction of impacted third molars is one of the most common oral surgeries performed in the dental clinic, which is often accompanied by many complications such as edema and trismus. Many methods have been used to alleviate these complications, such as drugs or physical therapy. Kinesiotape (KT) has recently spread as a popular physical method for eliminating complications after surgical extraction of lower third molars after its long-term use in sports medicine and injuries of the musculoskeletal system. The current study aimed to study the effect of using KT (Kinesio® Holding Corporation, Albuquerque, NM, USA) on both edema and trismus after impacted third molar extraction. This study was designed as a randomized controlled clinical trial using the split-mouth technique and included 25 patients with radiographically symmetrical lower third molars from patients. All surgical extractions were performed by a single surgeon under sterile conditions according to the standard surgical protocol after that one group applied KT and the other group applied cryotherapy. Edema and trismus were measured in the first five days. Data was collected and analyzed by SPSS software (IBM Corp., Armonk, NY, USA). The mean change in the total linear facial measurements in the experimental group (Kinesio Group) was 12.32 mm three days after surgery, and then this value decreased to 6.80 mm, while the average increase in the control group (Cryo Group) was 17.00 mm after three days, then the value decreased to 9.68 mm five days after surgery. Regarding the changes in the amount of maximum mouth opening after surgery, the results were similar between the Kinesio Group and the Cryo Group, as there were no significant differences between the two groups (P<0.05). This study concluded that KT was superior to cryotherapy when studying edema. The current study also concluded that the mouth opening was similar between the two study groups.

P-320 Ovarian tissue attached to stripped endometriomas: transforming the collateral damage to a potential source for oocyte preservation?

Abstract Study question To determine (antral) follicle density in the ovarian cortex tissue attached to stripped endometriomas and patient- and surgical characteristics affecting this density. Summary answer Ovarian tissue attached to stripped endometriomas offers a non-invasive source for antral follicles. Research with fresh tissue is necessary to further asses the quality. What is known already Ovarian endometriosis is associated with diminished ovarian reserve due to the disease itself as well as damage caused by excisional surgery, which may result in subfertility. When resecting endometriomas with the stripping technique, in the majority of cases, a thin line of adjacent ovarian cortex is attached to the endometrioma. Data regarding density and maturation of the follicles in this tissue are conflicting in previous publications. This study aims to quantify and characterise follicles and in particular antral follicles in ovarian tissue surrounding resected endometriomas as these may serve as a potential oocyte source for in vitro maturation (IVM). Study design, size, duration A retrospective cohort study was conducted at the Leiden University Medical Centre and the Endometriosis in Balance endometriosis expertise centre in Haaglanden Medical Centre (The Netherlands). Pathology slides of patients (≤50 years) that underwent uni- or bilateral endometrioma resection between 2011 and 2021 were analysed for the presence of follicles. Participants/materials, setting, methods Histological slides of previously removed endometriomas were assessed according to maturation and follicular density. Gougeon’s original follicle classification was modified by adding additional intermediate stages. Immunofluorescent staining of antral follicles in a subset of endometriomas was also performed. Main results and the role of chance In 90 out of 96 included endometriomas (93.7%), ovarian tissue attached to the cyst wall was observed. 1944 follicles at different maturation stages were identified (3 follicles/mm3). Follicle density was negatively associated with age (p &amp;lt; 0.001). Antral follicles (&amp;lt;7mm diameter) were present in the ovarian tissue attached to 35 endometriomas (36.5%) derived from younger patients compared to endometriomas where none were detected (30 versus 35 years, p = 0.003). Antral follicle density was 1 follicles/mm3. Based on immunofluorescence, healthy antral follicles were identified in 2 out of 4 examined endometriomas. Limitations, reasons for caution Tissue analysis was constrained by number of available pathology slides per patient, not fully representing the follicle distribution in the removed ovarian tissue. Immunofluorescence was performed on paraffin embedded tissue derived from a small number of endometriomas. Future research with fresh tissue is necessary to further assess viability. Wider implications of the findings Ovarian tissue attached to stripped endometriomas holds potential as a non-invasive source for antral follicles. In theory, application of IVM could be an interesting alternative fertility preservation option in young patients with endometriomas who undergo cystectomy in order to transform the surgical collateral damage to a potential oocyte source.

Robotic-Assisted Laparoscopy Excision of a Severe Form of Diaphragmatic Endometriosis: A Retrospective Study of 60 Patients

To assess the feasibility, effectiveness, and safety of the robotic surgical approach in the treatment of severe diaphragmatic endometriosis (DE). Retrospective single-center study using data prospectively recorded in the Franco-European Multidisciplinary Institute of Endometriosis database and the National Observatory for Endometriosis database. Tertiary referral center. Endometriosis care center. Sixty consecutive patients undergoing robotic excision of severe DE from January 2020 to July 2023. Robotic excision of severe DE. Categorical and continuous variables were evaluated and compared using descriptive statistics. A p value of <.05 was considered statistically significant. Full-thickness diaphragmatic resection was performed in 76.7% of patients (46 of 60) and partial diaphragmatic muscle resection in 10% of cases (6 of 60). Peritoneal stripping technique was performed in 60% of patients (36 of 60), divided as follows: as the only technique in the case of extensive superficial diaphragmatic involvement in 13.3% of cases (8 of 60), in addition to full-thickness or partial diaphragmatic resection in the case of concomitant multiple foci in 46.7% of patients (28 of 60). Median operative time was 79.6 minutes with no statistically significative difference related to the surgeon performing surgery (p >.05). Intraoperative and postoperative complications occurred in 1.7% (1 of 60) and 6.6% of cases (4 of 60), respectively. Diaphragmatic hernia (Clavien-Dindo 3b) was the most common postoperative complication and required surgical repair in all cases. Median hospital stay was 24 hours. The rate of patients with complete recovery from DE symptoms has gradually increased during follow-up, reaching 89% after 12 months from surgery. In this case series, robotic treatment of severe DE in expert hands was feasible, effective, and safe.

Stripping the catheter: A new device for an old technique.

Fibroblastic sleeve is a common pathophysiological phenomenon characterized by the formation of a mixed fibrous-collagen tissue encasing the outside of venous access devices. Although it nearly always presents asymptomatically, this catheter-related complication represents one of the leading culprits of venous catheters malfunction. Several techniques have been described for the management of dysfunctional catheters secondary to fibroblastic sleeve, including medical therapy, catheter exchange, balloon angioplasty, and percutaneous stripping. However, there is no common consensus for the treatment management in patients who present contraindications to surgical port removal. This report illustrates the case of a port catheter malfunction due to a fibroblastic sleeve in an oncological patient with a high risk of bleeding. This was effectively treated with a minimally invasive stripping technique using an off-label device for mechanical thrombectomy, namely the ClotTriever system (Inari Medical, Irvine, CA).

New methodological approach for deep penetrating geochemistry and environmental studies, Part 2: field determination of Co(II)/Ni(II) and Pb(II)/Zn(II) of on-site soil extractions by electrochemical stripping techniques

In the framework of deep penetrating geochemistry for mineral exploration, we report a field electroanalytical method using disposable screen-printed working electrodes able to quantify metal pathfinders in partial extracts of soil samples at the nanomolar level on-site. Four metal pathfinders (Co, Ni, Pb and Zn) were chosen due to their geological interest and suitability of electrochemical detection. Square-wave anodic stripping voltammetry (SW-ASV) was developed for the simultaneous detection of Pb(II) and Zn(II) providing limits of detection (LOD) of 1.2 and 5.3 nM, respectively. A linear-scan cathodic stripping voltammetry (LS-CSV) methodology was developed for the joint detection of Co(II) and Ni(II) yielding LOD of 1.8 and 3.5 nM, respectively. Method validation was carried out on 14 upper B-horizon soil samples during a field survey. Two wet extraction procedures were applied for soil samples – a strong extraction using nitric acid (HNO 3 ) and a weak extraction using calcium chloride (CaCl 2 ). Excellent agreement between electroanalytical methods and inductively coupled plasma mass spectrometry (ICP-MS) was found for Pb(II), while a small underestimation was observed for Zn(II). For Co(II) and Ni(II) the LS-CSV measurements in the HNO 3 extractions were impossible due to the change from low pH to pH to 7.15 which induces precipitation of iron and aluminium. For the CaCl 2 extractions, the Co(II)/Ni(II) results obtained by LS-CSV were in excellent agreement with ICP-MS measurements.

Implementation of Live Forensic Method on Fusion Hard Disk Drive (HDD) and Solid State Drive (SSD) RAID 0 Configuration TRIM Features

One of the solutions used for access speeds is to maximize non-volatile storage functions by a conventional Hard Disk Driver with Solid State Drive that has the TRIM architecture using the Redundant Array of Inexpensive Disks 0 configuration or the commonly known RAID 0. RAID 0 is a stripping technique that has the highest speed among other RAID configurations. However, this configuration has a disadvantage in that when there is damage to one of the storage disks all the data will be corrupted and lost. It's becoming one of the challenges in digital forensic investigation when it comes to computer crime. Furthermore, this research uses experimental practices using live forensic methods to perform analysis and examination against the merger of HDD and SSD configuration RAID 0 TRIM features. The expected is an overview of the characteristics of recovery capability to find out the authenticity integrity values of files that have been lost or permanently deleted on both TRIM SSD functions disable and enable. Furthermore, this research is expected to be a solution for the experimental and practical investigation of computer crime especially in Indonesia given the increasing development of technology that is directly compared with the rise in computer crime.

The impact of ovarian endometrioma and endometriotic cystectomy on anti-Müllerian hormone, and antral follicle count: a contemporary critical appraisal of systematic reviews.

Currently, three crucial questions regarding the reliability of ovarian reserve measures in women with ovarian endometrioma during the reproductive age are being discussed. Firstly, the effects of endometriotic cystectomy on short and long-term ovarian reserve. Secondly, the accuracy of serum anti-Müllerian hormone (AMH) and antral follicle count (AFC) in estimating ovarian reserve in these cases. Thirdly, the impact of endometrioma itself on the ovarian reserve over time in such cases. The purpose of the present review is to critically assess available systematic reviews and meta-analyses that have explored these questions. Nine eligible reviews were found following a systematic search on PubMed.com and similarly assessed. These reviews varied considerably regarding the level of evidence, as per an identical comprehensive scoring system. Moderate to high-quality evidence demonstrates that endometriotic cystectomy, by the stripping technique, adversely affects ovarian reserve in the short and long term, up to 9-18 months post-surgery. Damage to ovarian reserve was considerable but more pronounced in bilateral cases than unilateral cases, equivalent to 39.5% and 57.0%, respectively. Repeat endometriotic cystectomy is detrimental to ovarian reserve. The impact of endometrioma diameter on ovarian reserve before or after surgery is still unclear. Moderate to high-quality evidence, relying on simultaneous assessment of both ovarian reserve measures, shows that AMH is sensitive while AFC is not in cases undergoing ovarian cystectomy. AMH should be the biomarker of choice for counseling and managing women with endometrioma in their reproductive age, especially before surgery. While there is some evidence to show that endometrioma per se may harm ovarian reserve, this evidence is not robust, and there is good-quality evidence to challenge this notion. It is necessary to conduct further targeted RCTs, systematic reviews, and meta-analyses based on solid methodological grounds to increase the level of evidence, refine quantitative estimates, investigate open questions, and decrease heterogeneity.

Comparison of Dorsal Preservation Rhinoplasty Techniques: Functional and Aesthetic Review of Subdorsal Septal Strip Methods.

Objective: To compare subdorsal strip excisions in patients undergoing dorsal preservation (DP) rhinoplasty using patient-related outcome measures (PROMS). Methods: Patients were treated from 2020 to 2022 using the modified subdorsal strip method (MSSM) or Z flap approach. A two-sample t-test determined whether there was a difference in functional and aesthetic scores using the NOSE, Sinonasal Outcome Test (SNOT-22), SCHNOS, and ESS scales. Results: Seventy-one primary rhinoplasty patients met inclusion criteria at 12 months with an average age of 23 years (62 female, 9 male), with 35 (49%) undergoing the MSSM technique, while 36 (51%) receiving the Z flap. PROMS at 1, 3, 6, and 12 months postoperatively were compared. The average preoperative and postoperative NOSE score was 9.36 and -4.4 (standard deviation [SD] 3.1, p < 0.001). The average preoperative SNOT-22 score was 23.9 and -16.4 (SD 10.2, p < 0.001). ESS scores was average was 6.2 and -1.6 (SD 3.2, p = 0.01). The average SCHNOS total, functional, and cosmetic scores were 27.6 (6-47), 8.2 (0-20) and 18.7 (0-37), respectively, and -5.7 (SD 8.2, p < 0.001), -5.73 (SD 6.24, p < 0.001), -18.1 (SD 9.7, p < 0.001). No significant complications were found and no difference in PROMs among groups. Conclusion: There was no difference in septal strip techniques as evaluated by PROMS.

Transforming waste cellulosic fabric dyed with Reactive Yellow C4GL into value textile by a microwave assisted energy efficient system of color stripping

A million ton of cotton fabric is wasted during cutting process in garment industry as well as in textile dyeing industry due to faulty dyeing. Color stripping of cotton fabric has become a significant challenge in the textile industry because the harsh chemicals used in chemical stripping processes affects the quality of fabric very badly. Conventional stripping methods lead with severe effects due to prolonged treatment time and high chemical concentrations. Recently, microwave-assisted stripping techniques have been emerged as effective alternatives to improve stripping efficiency. In this research, the developed microwave assisted stripping system is improved by the application of Urea, which is utilized as a microwave absorber to further reduce stripping time, temperature, and chemical concentration kept focus on quality parameters of recycled cotton fabric. This study inspects the efficiency of microwave absorber-assisted alkali hydrolysis and reduction in terms of dye-fabric bond cleavage, chromophores removal, chemical consumption, and processing time and compared with sequential stripping, microwave assisted stripping without absorber and conventional methods. The results indicated that microwave absorber-assisted alkali hydrolysis and reduction achieved 90 % stripping efficiency by using lowest concentrations of chemicals, while sequential stripping yielded a stripping efficiency of 96 %. Similarly, microwave absorber assisted methods resulted in minor loss in tear strength and weight. These outputs highlight the superior performance of microwave absorber-assisted techniques, demonstrating their efficiency, novelty, time-saving nature, and reduced damage compared to other methods.

THE ROLE OF COMICS IN FACILITATING POSITIVE INTEGRATION IN THE CLASSROOM

In any field of activity, communication is the glue that fosters good understanding and healthy relationships between living beings. Referring strictly to didactic communication, it is imperative due to the fact that the educational act relies on all types of communication in order to lead to the success of the educational act which is done, as we know so well, through the activity of learning which must be done voluntarily, by the learner. In an ever-changing society, where parents are busy and find it difficult to take the time to communicate with their children, using the after-school services of schools and various organizations, it is up to the teacher to communicate effectively and to help the pupil to develop his or her intellectual, mental, physical, etc. skills. This article aims to show how we can facilitate a sense of well-being in the school environment using the comic strip technique.

Effect of Dorsal Preservation Techniques on Septum Strength: An Experimental Animal Study.

This experimental animal model study investigates the impact of different methods employed in preservation rhinoplasty (PR) on the strength of the nasal roof, focusing on three techniques: high strip, low strip, and intermediate strip. Using 15 lamb heads as surgical models, the study addresses key questions related to the strengths of each PR techniques, the influence of septal cartilage harvesting on septum strength, and the effectiveness of spreader grafts for stability. The research involves detailed dissection steps and measurements at various nasal points, evaluating the resistance at each stage. Results indicate that the low strip technique demonstrates the most significant reduction in strength. Furthermore, the combination of PR techniques with structural grafts, specifically spreader grafts, is assessed, revealing the classical rectangular spreader graft to be more effective in stabilizing the dorsum. Despite the limitation of using the lamb heads as models, this study offers valuable insights into the effects of PR on nasal septum strength and provides a foundation for further research on the biomechanics of preservation techniques.
